I don't remember not liking
The Wizard of Oz. The movie, anyway. I've never read the book. I don't know that we watched it every year when it came on TV as kids, but I've seen it often enough, including in film school and then several times afterward. We've got it floating around on DVD here somewhere.
That said, I didn't make it through the Fairuza Balk starring Return to Oz, nor a recent SyFy Channel attempt at an update.
And while I don't talk about it much, I more or less grew up going to the theater all the time, going to see musicals, drama, comedy, what-have-you, in venues from college campuses to community playhouses to the bigger venues in Houston (no, we didn't fly to New York to see shows). In addition, I did a bit of my own "acting" back in high school, but wasn't actually any good. In general, though, all that left me with a soft spot for live performance.
Here's the deal: going to see plays is @#$%ing expensive. I tip my hat to my folks, because I only understood in the abstract what a big deal it was to include their stupid kid in outings to what had to have been pretty pricey shows. Most of which I very much enjoyed, but, still. Now that I'm paying for it, I better see a flying monkey or two for my dollar, and I'm not going to wind up going all that often.
I was a bit torn about going to see Wicked as I'm never really sure what I'm getting with a touring Broadway Show in the era where Lion King is a big draw (I am the one person in America who was sort of non-plussed with the magic of Julie Taymor's puppets when I saw the show in Arizona) and Spider-Man with a soundtrack by U2 seemed like a good way to fill seats. Basically, I sort of think of musicals as a showy stage production more than I think of them as a particularly powerful way to communicate a narrative. There's a hell of a lot of difference between a revival of The Music Man and By the Skin of Our Teeth. But it can work.
